Letters Patent No. 105,294, dated July 12, 1870.

The Schedule referred to these Letten Patent--and-making pel-t 0f the lame To all whom it may concern Be itpknown tbatI, ERAsMUs W; Bnclgnr'r, of McGonnellsvill, Morgan county, Ohio, have invented a new and useful Improvement on Circular-saw Machines, of which the following is a clear, full, and exact description, reference being had 4to the accompal nyiug drawing, in which- Figure Iis a perspeetive'view ot a saw with my improvement attached thereto. v

- Figure 1I is the slide, represented on the head-plate 'with side view broken.

Fi re III is a separate view of the roller. Theobiect of my invention is to alord greater security against the springing of the timber to be sawed, and the cramping of the'saw, and also to furnish a means for securing a uniform thickness of the lumber sawed.

To enable others skilled Ain the art to make and understand my improvement, I will proceed to describe how I havecari'ilit out.

In the said drawing- A represents a saw-frame;

s h, the saw-shaft; and

b l1, the circular saw.

B is head-plate, secured to tllecorner of the sawfra'me by means of bolts, and having a flanged top, over and .upon which the slide H mores by means of 'its gib form.

R is a roller, secured to the slide H, and held firmly in position when in use by the dog O,w hicl1'also prevents the sldefiom moving when the springing force of the: log to be sawed is brought againstA the roller R, thus' securing a uniform thickness to the llumber sawed, and preventing the' saw from being cramped by the springing of the timber. 1 f vI am'aware that the application of head-plates and rollers to saw-frames is not new.; but

What I cleim, and. desire to secure by Letters Patent, is

The head-plateB, with a flanged top, in combination'with the gib-formed slide H, roilerR, and-dog 0,

all mnstructed and operating substantially as and for thepurpose set forth.- E. NV. BEOKEIT.l
